Title
R. S. CHHOKAR; R. K. MALIK Weed Technology 2002. doi:10.1614/0890-037x(2002)016[0116:irlcpm]2.0.co;2
Other claims from this paper (14)
- Observation Six of 10 littleseed canarygrass biotypes were resistant to isoproturon.
- Observation Resistant biotypes had 50% growth reduction values 5 to 10 times greater than the most susceptible biotype.
- Observation The resistant biotypes came from areas where isoproturon had been used continuously for more than 10 years.
- Intervention effect Postemergence isoproturon at 1,000 g/ha 32 days after sowing failed to control littleseed canarygrass under field conditions.
- Intervention effect Wheat grain yield decreased by 65% compared with the weed-free control after postemergence isoproturon at 1,000 g/ha.
- Intervention effect CGA 184927 at 50 to 60 g ai/ha was effective in wheat against isoproturon-resistant littleseed canarygrass.
- Intervention effect Fenoxaprop-p-ethyl at 100 to 120 g/ha was effective in wheat against isoproturon-resistant littleseed canarygrass.
- Intervention effect ICIA 0604 at 350 g ai/ha was effective in wheat against isoproturon-resistant littleseed canarygrass.
- Intervention effect MON 37503 at 25 g ai/ha was effective in wheat against isoproturon-resistant littleseed canarygrass.
- Intervention effect Use of these herbicides increased wheat grain yield by 200% or more compared with the weedy check.
- Intervention effect MON 37503 at 25 g ai/ha was the best of the herbicides tested.
- Intervention effect MON 37503 at 25 g ai/ha produced wheat yield similar to the weed-free control.
- Recommendation Growers should follow herbicide and crop rotation to avoid development of herbicide resistance.
- Recommendation Integrating crop and herbicide rotation with cultural and mechanical weed control could be a long-term strategy for resistance management.
